Abstract

Patente de Invenção: <B>"MéTODO PARA MICROENCAPSULAçãO DE UMA SUBSTâNCIA SóLIDA"<D>. Método para microencapsulação de uma substância sólida biologicamente ativa que é caracterizado pela polimerização de um monómero que é polimerizável por condensação em uma dispersão contendo i) uma solução contendo uma substância não iónica e ii) a substância sólida biologicamente ativa que é insolúvel ou difícil de dissolver na referida solução, em que a substância não iónica é eficaz para dispersão da substância biologicamente ativa na referida solução, é um método efetivo para a produção de uma composição microencapsulada sem agregação.Invention Patent: <B> "METHOD FOR MICROENCAPSULATION OF A SOLID SUBSTANCE" <D>. Method for microencapsulation of a solid biologically active substance that is characterized by the polymerization of a monomer that is polymerizable by condensation in a dispersion containing i) a solution containing a nonionic substance and ii) the biologically active solid substance that is insoluble or difficult to dissolve in said solution, where the non-ionic substance is effective for dispersing the biologically active substance in said solution, it is an effective method for producing a microencapsulated composition without aggregation.
